Elizalda, a 10-year veteran, was arrested in an early morning raid on his home in Chula Vista. Agents seized cash and two luxury cars.

Elizalda's arrest came a day after another border officer was arraigned on similar charges of accepting more than $500,000 in bribes from smugglers driving illegal immigrants through the border crossing at Otay Mesa, several miles east of San Ysidro. Investigators said they believe the two cases are unrelated.

Attempts to contact Elizalda's home were unsuccessful and the name of his lawyer was not known.
